**1. Homework Statement**

**2. Homework Equations**

Series: R(eq) = R(1) + R(2) + . . .

Parallel: [tex]\frac{1}{R(eq)}[/tex] = [tex]\frac{1}{R(1)}[/tex] + [tex]\frac{1}{R(2)}[/tex] + . . .

**3. The Attempt at a Solution**

I'm confident w/ (b) i think, but i just want to know if i'm going about these correctly.

for (a), since nothing is in the center wire, that can be treated as a node. If that's the case, the top 2 and the bottom 2 can be treated like they're in parallel respectively, then added like they are in series. R(eq) = R(1)

for (b), the two sides can be treated like they are in series, then those are added in parallel. R(eq) = [tex]\frac{R(1)}{2}[/tex]

for (c), I'm labeling directions of current, but i'm not sure which add in what way. Any help would be great.
